reflection and wrapTransform

[muzikathzi webforumsuser@macromedia.com]

Hi!

is it possible to change the transformation of a reflectionmap to for example cylindrical mapping?
this would make it easier to create natural reflections of an enviroment.

thanks

In order to improve realism, my graphic artist creates a panoramic texture
in Photoshop that he then uses as an enviroment map in 3DS Max. I just have
to set the shader blend parameters to whatever I wish for the reflectionMap
to render well once the scene is imported. Other than that, I don't need any
code.

You can fake a cylindrical reflection by using a texture that can wrap cylindrically, like the front, left, back and right sides of a skybox placed next to each other.

That way you'll have a 4:1 texture. When you apply it as #reflection, change the texturetransform's scale. Scretch the texture in the X axis by 0.25 times. That way only 1/4 of the texture will be visible in the model. Then you need to do some math to translate the texture accordling to the model's rotation relative to the camera, and you have a pretty fast and convincing envronmental map.

I´ve already tried this with a texture that consists with a red a green yellow and blue side (265x256, so the whole texture has the dimention 1024x356)
when I translate this texture along the x axis the edge between the colors doesn´t appear as a staight line, because the reflectionmap isn´t mapped cylindrical.

i hope you understand what i mean...it´s difficult to explain
